Stage 1: INITIAL PROPOSAL

Brain Storming:

1. Which sport causes the most head damage over time?
- I am interested in this topic because I love sports, however finding raw data was difficult therefore i would not perfer to do this topic
2. Comparing cost of care per inpatient day to mortality rate
-I feel this topic to be in my interest however it is not quite interesting because it is about money and therefore i will choose to keep looking
3. Comparing the Hospital Mortality Rate index by institution to the year
- This topic interests me because I plan to go into the medical field and it is interesting to find out where i would have the highest rate to survive.

Background Information:
Hospital Mortality Rate Index- A key statistic that consumer groups and the media often use when comparing hospital report cards and national rankings. The statistic called Mortality Index means
- a number above 100 indicates a hospital had more deaths than expected within that given year
- a number lower then 100 means there were fewer deaths than expected.
a hospital with a lower mortality index may not be a better hospital for patient care, but rather a place where the patient mix has been refined or limited. However when comparing it to how much each hospital spends a year in acute expenses there may be some correlation of which hospital would be the wiser choice to go to.
Total Acute Expenses- these cost estimates are for the hospital stays with higher complexities. Acute meaning severe.

Variables:
Variable independent (Y): Acute Expenses in the years 1999-2005
Variable Dependent (X): Mortality Index Rate 1999-2005


Hypothesis:
I believe the acute expenses will impact the mortality rate index. The more money spent on acute expenses the lower the mortality rate index will be, and therefore the safer the hospital.

Question: Does the acute expenses play a role in the mortality rate index of the hospitals listed below in canada in the years of 1999-2005.

Institutions I have decided to analyze:Grand River Hospital, North York General, Ottawa Hospital Montfort, Rouge Valley Toronto,St. Joseph's Sarnia, Timmins and District General Hospital, Stratford General Hospital, Trillium Hospital Missisauga, Windsor Hospital and Thunder Bay Regional.oes the acute expenses play a role in the mortality Years i have decided to analyze - 1999-2000,2000-2001,2001-2002, 2002-2003, 2003-2004, 2004-2005

One variable Analysis:

Two Variable Analysis:


Sampling Bias:
  • There is non response Bias within the data due one hospital (Grand River) not participating to hand in their information for the year of 2000-2001. Therefore they are under represented in the study.

  • The data is legitimate and collected from a trusted source. The source being from The Ministry of Health and long-term Care Health Data Branch. (Mohltcfim.com)
Hidden Variable:
the data collected should be random sampling or systematic because the data collected is from hospitals in different cities with different populations in that city. Also the type of area the hospital is such as a high crime might impact the hidden variable of how
Sampling Technique:
  • Cluster Sampling- certain groups are likely to be represented of the entire popuation
  • Therefore I selected randomly a group of hospitals that all fell under the category of large community hospitals



Conclusion:  In conclusion, my hypothesis was proven incorrect. I originally stated it would have a moderate negative relationship but in fact it was a weak negative relationship. This may be because of only using acute expenses instead of the total expenses of the hospitals, however the total expenses was not available. It may also have to do with the content only being within 10 hospitals and 6 years.
